State-of-the-art Equipment to get the job done right

DISPLACEMENT

Displacement involves moving gases or liquids to make it safe to work in a particular section of a facility. Blackstone Pipeline’s experienced team and state-of-the-art nitrogen pumping equipment is designed to execute reliable displacement programs with predictable results. 

PNEUMATIC TESTING

Testing a facility’s mechanical integrity prior to use is fundamental to maintaining safe and effective operations. Blackstone Pipeline provides thorough and reliable pneumatic pressure testing services using data acquisition and analysis to provide accurate results that exceed the requirements for certification.  

Leak testing

Helium leak testing helps find small leaks with inert, non-volatile compounds. If leaks are found in the system, the pressure is bled off, the connection is repaired, and the process is repeated until all leaks are eliminated. Additionally, this method of testing can help discover other issues, and can be used to simulate operational situations. 

INERTING

Nitrogen inerting is a technique that provides a safe working environment for carrying out hot work maintenance in the presence of hydrocarbons. Nitrogen inerting with Blackstone Pipeline is a fast, reliable, and cost-effective process that eliminates the risk of hydrocarbon explosions.

PURGING

Purging involves moving or diluting gases or liquids until it becomes safe to work in that section of the facility or pipeline. The process is achieved using gas, often nitrogen, and requires detailed calculations and simulations. With our experienced team and state-of-the-art nitrogen pumping equipment, we design and execute reliable programs with predictable results. 

FREEZE PLUGS

Pipelines and operational facilities often require work to be done on active lines. Freeze plugs provide the ability to isolate a section requiring maintenance instead of purging the entire line.

Using a “jacket” injected with liquid nitrogen we create a freeze plug that isolates part of the line. Freeze plugs can also be used to locate small leaks during hydrotesting, by reducing the length of pipeline by half with every isolation.

Back Pressure Pad

Back pressure pads can play an important role in effective, efficient and safe pipeline operations. Using nitrogen, back pressure pads address two critical elements of flooding a pipeline with product: safety & product separation. 

Continue reading

Product separation
Product separation is a serious issue that can cause the collapse of a pipe. We engineer back pressure programs, specifically designed to hold fluid back and avoid any separation.

Safety
Blackstone Pipeline uses back pressure pads to create an inert environment that eliminates the risk of an explosion for safer operations.

Hydrotest

Hydrotests can play an essential role in establishing and maintaining effective pipelines. Our experienced project managers, operators and engineers can determine material strength, find gross leaks, and provide hydrotest solutions for pipelines, tanks, vessels, and facility piping.

Isolation

When a valve cannot be isolated and work is required downstream, or when searching for leaks during a hydrotest, nitrogen assisted freezing and viscous fluid sealing can be effective solutions. Blackstone Pipeline’s nitrogen assisted freezing process uses closed-chamber freeze isolation to ensure safety, while temporarily quarantining the required section of pipe.

In the situation where a valve will not properly seal, and bypass is a concern, we have developed viscous fluid seal solutions to effectively address the issue. Applications include:

Water
Hydrocarbon
Methanol
Glycol

DRYING

Drying is a critical step for maintaining the integrity and performance of your pipeline. Pipeline drying can be achieved using a variety of methods including nitrogen, air, methanol, and swabs. 

Continue reading

Blackstone Pipeline’s engineered drying service provides up to -40°C/F system dew point. This ensures water will not contaminate product pipelines, cause corrosion, or cause process upset. Additionally, drying helps in the elimination of hydrates in gas processes and pipelines.

Leak Check

There are many different reasons to leak test a pipeline and a variety of methods that can be used. Many leak testing methods rely on changing the system pressure, and/or injecting and detecting a chemical. Our expertise in pressure pumping and chemical processes enables us to perform expert leak detection services using a wide range of methods.

Pigging/Cleaning

The most effective pipeline cleaning and pigging comes from a thorough investigation and understanding of line contents and deposits. Our system-specific programs use selective chemistries for black powder removal and abatement, wax removal, asphaltene removal, and engineered viscous fluid programs for inorganic deposit removal. 

Continue reading

These proven chemical remediation techniques, combined with the best pigging technologies, ensure you get a comprehensively cleaned system.

Corrosion Inhibitor Batching

When a pipeline isn’t going to be used for an extended period of time, the possibility of corrosion can increase. Corrosion can affect the lifecycle of your pipeline, as well as its structural integrity. The introduction of corrosion inhibitors is an effective way to control this issue.

Continue reading

To be successful with this method, it is essential to use the right chemistry for your unique situation. Blackstone Pipeline has extensive experience in this area – we perform a thorough investigation and use continuous and batch injection equipment to determine and apply fit-for-purpose inhibitors that stop corrosion and maintain pipeline integrity. 

Leak Detection

There are many different reasons to leak test a pipeline and a variety of methods that can be used. Many leak testing methods rely on changing the system pressure, and/or injecting and detecting a chemical. Our expertise in pressure pumping and chemical processes enables us to perform expert leak detection services using a wide range of methods.

The process is achieved using gas, often nitrogen, and requires detailed calculations and simulations. With our experienced team and state-of-the-art nitrogen pumping equipment, we design and execute reliable programs with predictable results. 

FLOW PROVING

Leak detection is critical to maintaining pipeline integrity. Our flow proving technique involves simulating leaks at a variety of different flow rates. This procedure assesses the accuracy and reliability of your leak detection software to discover any issues and ensure safe and effective operations. 

ISOLATION

When a valve cannot be isolated and work is required downstream, or for leak detection during a hydrotest, nitrogen assisted freezing and viscous fluid sealing can be effective solutions. Blackstone Pipeline nitrogen assisted freezing uses closed chamber freeze isolation to ensure safety while temporarily quarantining the required section of pipe.

PIGGING & CLEANING

The most effective pipeline cleaning and pigging comes from a thorough investigation and understanding of line contents and deposits. Our system-specific programs use selective chemistries for black powder removal and abatement, wax removal, asphaltene removal, and engineered viscous fluid programs for inorganic deposit removal.

GROUTING

Grouting, or filling a pipeline with cement, is an economical way to abandon the system. Using this in-place abandonment method requires a thorough analysis to ensure safety and structural integrity are maintained. Our experienced pipeline services team considers a wide range of factors to determine the best fill material, volume, and injection rates to be used, so you get a fit-for-purpose solution to get the job done right.
